IMPROVEMENT IN VALVES FOR WASH-BASINS.

Specification forming part of Letters Patent N0. 201,405, dated March19, 1878 application filed February 6, 1878.

To all whom it may concern:

Be itknown that I, J OHN S. GILBERT, of the city, county, and State ofNew York, have invented a new and useful Improvement in Valves forWash-Basins, of which the following is a specification:

Figure 1 is a top view of a wash-basin to which my improvement has beenapplied. Fig. 2 is a side view of the same, partly in section, throughthe line a; m, Fig. 1, to show the construction.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved attachment forwash-basins, to prevent the sewergas from escaping into the room throughthe waste-pipe, which shall be so constructed that it cannot be leftopen when the water is turned off, and cannot be left closed when thewater is turned on, and which shall be simple in construction andeffective in use.

The invention consists in the combination of the hinged or sliding valvewith a washbasin in such a way as to drop down and close theoverflow-holes when the water is turned off, and rise and uncover thesaid holes when the water is turned on and in the combination of thechain with the hinged or sliding valve, and the faucet, in such a way asto raise the said valve when the water is turned on, and lower it whenthe water is turned off, as hereinafter fully described.

A represents a wash-basin, and B represents the faucet, through whichthe water is introduced into the said basin. a are the holes throughwhich the overflow water passes into the waste-pipe. O is avalve, whichis hinged to the rim of the basin A, or to other suitable support, andthe lower side of which fits against the part of the basin A throughwhich the holes a are formed.

The lower surface of the valve 0 may be coveredwith leather, rubber, orother suitable material to cause it to close the holes a closely.

The valve 0 may be made hollow, and of such a weight that the water, asit rises in the basin A, will raise the said valve and uncover the holesa, so that the overflow water can escape freely.

The valve 0 may be made solid and heavy, and may have a chain, D,attached to its lower part. The other end of the chain D is attached tothe faucet B in such a way that it will be wound around the said faucetto raise the valve 0 when the faucet is turned to turn on the water, andwill be lowered when the water is turned off.

If desired, the valve 0 may be arranged to slide up and down in ways orguides instead of being hinged.

I am aware that it is not broadly new to stop the overflow-pipe of awash-basin to prevent sewer-gases from entering the apartment in whichthe basin is placed through the overflow opening; I therefore make nobroad claim to such invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The hollow valve 0 attached to the side of awash-basin, A, connected with the sewer, said valve being kept in placeby means of a hinge, or its equivalent, and opened by its own buoyancy,when the water is let on through the faucet, and to close air-tight whenthe water is let off through the plug in the bottom of the basin.

2. The valve 0, attached to the side of the basin, connected to thefaucet B by means of a chain, D, whereby when the faucet is opened thechain will wind around the faucet and lift the valve, and when thefaucet is closed the valve will fall against the side of the basin, andbecome air-tight, substantially as specified.
